The invention briey described consists of a wrapping machine comprisingthree successively actingfeeding and folding mechanisms. 15

'I'he wrapper is fed in the form of a paper strip or web across the pathof movement of the article and is fed at such a rate and severed at'such a point in the cycle of operation that it is held by the feedingmeans as the sheet or web is folded 2.) across the top, advance end andbottom of the article. The cutting mechanism cuts the 4strip or web whenthe proper length has been fed.

The article and wrapper are fed by endless feeding members along theinitial table or support to the second support. The article and wrapperare then fed by endless feeding means along the second support andduring their passage along this support tucks are placed in the advanceends of the Wrapper and the ends are folded across the ends of thearticle. The second feeding mechanism may be speeded up to operate at afaster rate of speed than the rst feed so as to"take the article andwrapper away" from the first feeding mechanism. I

The article and wrapper are then discharged from the second support to athird table or support. They are initially fed along this support by areciprocating feeding member and are then engaged and. fed bycontinuously acting feeding 40; members. During the movement along thethird support the rear ends of the wrapper are tucked and are lfoldedacross the rear end of the article,

thus completing the wrapping operation.

In` the particular form of the invention shown the last named supportand feeding means are disposed at right angles to the first two supportsand wrapper.

Further details of\the invention will appear from the followingdescription. In the form of the invention illustrated in the drawings,there are three sets of operating mechanism which operate successivelyon the article Furthermore, there are three supports or tables alongwhichy the article and wrapper are fed. Ihe rst supporting table isshown. at A, the second at Band the third at C. It will be noted thatthe support or table C is disposed at right angles to the supports A andB. 'I'he support A comprises two sections 38 and 3| which are separatedby a gap or space 32.

The articles X to be wrapped are disposed in a -hopper 33 which extendsabo've the support A 'I'he endless feeding members 31 and 38 aresupported at one end on sprockets 39 carried by a shaft 48 mounted in aframe 4|. Atthe other ends the feeding members 31 and 38 pass aroundidler sprockets 45 and 46 mounted on stub shafts 41 carried bythe framemembers 4|. idlers45 and 48 the feeding members 31 and 38 'pass aroundsprockets 48 and 4x9 mounted on a shaft 58. The feeding members 31 and38 pass over the sprockets -48 and -49 and beneath sprockets and 52carried by a shaft 53. The shafts 58 and 53 are driven by a chain 55which engages sprockets 58 and 51Imounted on the shafts58and 53 and alsoengages a sprocket 58 mounted on a shaft 59 carried by the .framemembers 4|.

'Paper feed mechanism The paper for the wrappers, which in this in- Ystance may be wax paper or a heat sealing paper.

` presses the roll 83 toward the roll 62 to maintain the desired feedingpressure between the rolls.

The paper feed rolls are driven from a shaft 18 on which the rotarycutting knife is mounted, as hereinafter described, by means of thegearing shown in Fig.V 13. From this figure it will be noted that a gear1| mounted on the shaft 18 meshes with a gear 12 carried by an arm 13pivoted on the shaft 64. 'I'his shaft, on which is mounted the roll 82,has secured thereto a gear 14 which meshes with a gear 15 mountedon theshaft 65 which carries the fe'ecl roll 63.

The arm 13 can be adjusted about the axis of the shaft 64 to permitdifferent sizes of gears to be used in the place of the gear 1|, thusvarying the speed of rotation of the feed rolls and the rate and lengthsof paper fed thereby. The arm 13 is held in adjusted position by meansof a nut or bolt 16 which passes through an arcuate slot 11 formed inthe upper end 18 of the arm.

From the Paper cutting mechanism The paper cutting mechanism comprises arotary knife 88 carried by an arm 8| fixed to the shaft 18 and astationary knife. 82 which `is adjustable toward and away from the axisor shaft 18 by means, of a screw 83. The shape of the knife 80 is shownin Figs. 14 and 15 from which it will be seen that the knife isV-shaped, the central portion of the knife .s hownat 85being disposed inadvance of the end portions shown at 86. The knife is beveled, as shownin Fig. 14.

The blanks cut from the paper strip by the knife take the form shown inFig. 1'9, the object tral portion 81 ofthe V projects above the articleand forms a tab by means of which the wrapper can be pulled away andremoved from the article. yThe rotary cutting knife is operated by asprocket and chain connection to the shaft 58. This shaft has mountedthereon a sprocket 88 which is connected by a chain 89 to drive asprocket 9 8 which is adjustably connected to a disk or wheel 9| fixedto the shaft 18. This adjustable connection is shown particularly in-Figs.

adjustment between these two parts can be secured. For instance, sixteenopenings may be formed in the disk and fteen in the sprocket. 'IIhesprocket can be rotated on the disk to any desired position to adjustthe timing or opera.- tion of the cutting knife and when properlypositioned a screw or bolt 94 is passed through the opening 93 in thesprocket and is threaded into the opening 92 in the disk. Thus, theshaft can be properly timed to cut the paper in accordance with thelength fed by the feed rolls, it being remembered that the rate ofrotation of theseA rolls can be adjusted by changing the gear 1|. Itwill also be evident that the cutting of the paper must be'properlytimed with reference to the feeding of the article in order to feed thepaper to the desired extent through the gap or slot 32 between thesections 38 and 3| of the support A. The paper should be so fed andsevered that as the article engages the paper and feeds the paperforwardly on the support section 3| the free ends of the paper willproperly overlap the rear end of the article.

' As the article and Wrapper are fed over the support 3| they will bedisposed beneath a top wall |08 which is adjustably mounted above thesupport 3| and operates to holdthe wrapper down against the upper surfacof the article. The paper feed, article feed and cutter feed are sotimed that the article will engage the paper and be foldedV around theadvance end and top and bottom of the article before it is cut, the cutbeing made when the proper length has been fed to provide theoverlapping ends of the right lengths.

' `The article and wrapper are fed by the feeding members 36 between thewalls 3| and |88 and across the support vor table section 3| and aredischarged thereby to the second support or table .B. This support ortable comprises a pair of ward and away from each other by right andleft hand screws |03 and |03 formed on spindles ||0, |I0. These spindlesare connected by sprocket and chain connectionsvl I, H2. ||3 and one ofthe spindles has secured thereto a crank ||4 by means of which thespindles can be rotated. As these spindles are rotated the side walls|04 and |05 and the spaced supports |.02 and |03 are moved toward andaway from each other. The top wall above described extends above thesupport B as well as above the sup- POrt A.

The walls |04 and |05-have formed at the entrance end thereof tuckers||5, ||5 which tuck the advance edges of the wrapper against the ends ofthe article, one of the advanced edge tucks being shown at ||6 in Figs.16, `1'( and 18. Above the tuckers are formed slots ||1 which receivethe upper projecting end flaps or folds and below the tuckers are formedslots ||3 which receive the lower projecting end flaps or folds. Theupper slots are formed between the upper edges of the tuckers ||5 andthelower edges of adjustably mounted pieces ||9 having inclined upper edgeswhich engage inclined supports |2| and are adjustable relative thereto,being secured in adjusted position by nuts |22. This adjustment is madeto provide for different thicknesses of articles being wrapped.

The slots lead to downwardly inclined slots |23 which are formed betweenlower edges |24 of the side walls |04 and |05 andthe upper edges |25 ofthe tuckers ||5. lAs the upper end foldsy travel through the slots ||1and downwardly through the slots |23 they will be folded downwardly andinwardly against the ends of the article. After this fold has beencompleted the lower projecting end folds or flaps engage the upwardlyinclined slots |26 and are folded thereby upwardly and inwardly againstthe downwardly folded end flaps. Afterl these end naps have been foldedagainst the ends of the article the article is fed between the heaters|30 which cause the wax in the wax paper to be softened, thus sealingthe ends of the article.

The articles and wrappers are fed along the support B by means of spacedU-shaped feeding members which are carried by an endless belt or chain|36 mounted on sprockets |31 and |33. The sprocket |31 is secured to theshaft 59 which is driven in the manner hereinbefore described. From theshowing in Fig. l it' will be noted that the feeding members |35 aredisposed centrally and between the endless chains 31 and 33.Furthermore, these members are so spaced that they will move upwardly inthe direction of the arrow shown in Fig. 3 at a period in the operationof the vfeeding members 36 in which these members are out of the way solthat the members 36 will not be at any time disposed'in the path ofmovement of the members |35.

From the showing in Fig. 3 it will be noted that one of the feedingmembers |35 is disposed with the upper leg of the U-shaped member inengagement with the rear edge of the article, the overlapping end |40 ofthe wrapper being disposed between the two legs |4| and |42 of thefeeding member |35.

Fig. 4 illustrates the path of vmovement of the feeding member |35 as itleaves the article and wrapper and from this figure it will be notedthat the outer leg |4| o f the member |35 is in engagement with the end|40 of the wrapper and has folded this end downwardly. As soon as thefeeding member |33 moves away from the end |40 of the wrapper this endwill immediately snap upwardly to the position parallel to the upperoverlapping end |45.

' From the foregoing description it will be noted that as the articlesandY wrappers are fedvover the support B the front end tucks will beplaced-in the 'wrapper and the end flaps will be folded across the endsof the wrapper and sealed in folded position by the operation of theheaters. At this stage in the operation the wrapper has been folded inthe manner shown in Fig 16.`

, 'I'he final feeding operation ofthe feeding members |35 discharges thearticle and wrapper in the form shown in Fig. 16 to the third support Cwhich, as shown in Fig. 1, is disposed at right angles to the supports Aand B. The support C has a side wall which forms an abutment for thearticle and wrapper and engages the closed edge |5| of the wrapper. Atop plate |48 is adjustably supported above the support C and can bevertically adjusted, as shown at |49 in Fig. 1. laterally from the otheredge of the article, as shown in Fig. 3.

'I'he article and wrapper are fed along the support C by means of spacedfeeding members |52 carried by an endless carrier |53 mounted on ysprockets |54 and |55 carried by spindles |56 and |51. The spindle orshaft |56 is driven by a bevel gear connection |58, |59 to the shaft 53.

It has been found that the operation of the endless Afeeding members 53and members or lugs |52 at high speed causing the lugs to e'ngageagainst the sides of the article, tends to dent .in the article anddamage the package and for this reason the lugs |52 do not engage andfeed the article and wrapper immediately after it has been vdeposited onthe-support C. They are, however, fed by a reciprocating feedingmechanism illustrated particularly in Fig. 5. In this figure there isshown an arm 90 having an angular head on the front end thereofconsisting of an upper plate |9| adapted to engage over the top of thearticle and a rear plate |92 adapted to engage along the rear side ofthe article. The arm |90 is reciprocated back and forth on the support Cand is so timed as to engage and feed the articles after they have beendeposited on the support by the feeding members or lugs |35 or |80,hereinafter described. AAt its rear end the arm |90 is pivoted at |93 tothe upper end of a lever |94 which is mounted on a fixed pivot |95 andis provided intermediate its ends with a roller |96 disposeddnengagementfwith a cam |91 mounted on the shaft |56. A spring |98 engagesthe upper surface of the arm |90 and holds the front end of the arm orhead in engagement with the table or support C.

From the showing in Fig. 5 it will be seen that as the shaft |56 and cam|91 rotate the lever |94 will be oscillated about vits pivot |95 andwill reciprocate thearm 90 andthe feeding head formed on the front endthereof. A suitable The free ends of the wrapper project spring, asshown, is provided to press the arm and at the limit of the feedingmovement |90 the article and wrapper are moving at approximately thespeed of movement of the lugs |35 or |80.

The first operation performed on the suppoit C is to place the end tucks|60 and |6| in the Wraper members |05 which are formed on a disk |00mounted on a spindle |01 to which is secured a sprocket driven by thechain |00. From the showing in Fig. 10 it will be noted that the tuckerforms the tuck |00 and moves within the end |03 of the stationary tucker|02. Thus, the tuck |80 is guided beneath the stationary tucker and heldin position.

'I'he free ends |40 and |40 of the wrapper are folded inwardly againstthe rear end of the article by the operation of slots and |1| whichoperate in the same manner as the slots shown in Fig. 6. It will benoted that the upper end |00 is first folded downwardly and inwardlyagainst the tucked ends and against the end of the article and the lowerend |40 is then folded upwardly against the article and also against thefolded end |40. The completed wrapper is shown in Fig. 18 from which, asabove stated, it will be noted that the central portion of the 4end |40extends slightly above the upper surface of the article forming a tab. fl,

`In Fig. 20 there is illustrated a slightly different form of feedingmechanism for feeding the articles and wrappers over the support B. In

this embodiment of the invention the second feeding mechanism is mountedabove the support B instead of below the support. 'I'his mechanismcomprises a plurality of feeding members |00 which are carried by anendless carrier I 8| mounted on sprockets |02 and |02. With the form of#feed shown in Fig. 3 there is a slight pause between thedlscharge of thearticles and wrappers from the section 2| of support A to the support Band the feeding movement of the articles and wrappers along the supportB. However, with the form of feed shown in Fig. 20 there is no pausebetween these two feeding mechanisms and the feeding members |00 comeinto operation as soon as the feeding members 06 have finished theirfeeding operation. From the' showing at the right hand end of Fig. 20 itwill be noted that the upper flap |40 or upper free end of the wrappersnaps up as soon as the feeding membery |00 has finished its feedingoperation and lmoved upwardly awayfrom the article and wrapper. 'I'herotary tucker |00, moreover, insures the proper positioning of the upperflap |45 since the tucker bends the flap upwardly in case it has notalready snapped up.

In the embodiment of the invention shown in Fig. 21, the upper conveyor200 overlaps the de' livery end of the lower conveyor 20|. 'I'heconveyor 200 is driven at a faster rate than the conveyor 20|, by anysuitable driving connections and thus moves the article and wrapper awayfrom the feeding member 202 on conveyor 20| and prevents member 202 fromsnapping the lower flap downwardly as the member 202 moves downwardly.

Members 202 may be formed as shown in Fig. 22 tol engage the end of orrear edge of the article between the end edge portions vof the wrapper.

From the foregoing description it will be evident that simple,`practical and emcient wrapping mechanism has been provided and that thearticles will be quickly or rapidly fed through s,1ss,ses

the machine yand wrapper by the folding and wrapping mechanismdescribed. Furthermore. there is practically no interruption ito thefeed of the articles through the machine.- l
